SN74HC373DWR TI Latches | 20-SOIC | 8-Bit D-Type, Tri-State

Product Overview

The SN74HC373DWR from Texas Instruments is a high-performance octal transparent D-type latch with 3-state outputs. It is designed for 2-V to 6-V VCC operation, making it suitable for a wide range of applications. The device features eight latches with individual D-type inputs and Q outputs, controlled by a latch enable (LE) and output enable (OE) input. When LE is high, the Q outputs follow the D inputs; when LE goes low, the data is latched. The OE input controls the 3-state outputs, allowing connection to bus-oriented systems. The SN74HC373DWR is housed in a 20-pin SOIC package, offering a compact solution for data storage and bus driving.

產品概述

SN74HC373DWR 是德州儀器 (TI) 生產的高性能八路透明 D 型鎖存器，帶三態輸出。它設計用於 2 V 至 6 V 的 VCC 操作，適用於廣泛的應用。該器件包含八個鎖存器，每個具有獨立的 D 型輸入和 Q 輸出，由鎖存使能 (LE) 和輸出使能 (OE) 輸入控制。當 LE 為高電平時，Q 輸出跟隨 D 輸入；當 LE 變為低電平時，數據被鎖存。OE 輸入控制三態輸出，允許連接到總線系統。SN74HC373DWR 採用 20 引腳 SOIC 封裝，為數據存儲和總線驅動提供緊湊解決方案。
